is a specification.

- This invention relates to wrtain new andv useful improvements in anti-slipping devices for vehicle heels, and has particular reference to a device of that kind which is well adapted for application to the tread of a pneumatic tire for preventing slipping in inclement weather or to prevent the vehicle from becoming mired in mud holes or the like.

The invention consists in an improvement over the common form of endless skid chain novv in use and is adapted for a somewhat similar application to the wheel,

The primary object of the invention is to provide a device of the above kind which braces the desired qualities of simplicity d durability of construction, as Well as eciency in o oration.

Another ologect is to provide an anti-slippin device which embodies a novel and valuah e form of cushion tread by means of which shocks and jars are reduced to a minimum when employing the device,

@ther objects will appear as the nature of the invention is hotter understood, and the same consists in the novel iorrn, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawings and claimed in the drawings, wherein like reference characters indicate corresponding parts throughout the several views,

Figure it is a side eievational view showing an anti-slipping device constructed in accordance with the present invention and applied to a disc Wheel.

Figure :2 is a top plan viev. oi the antislipping device.

F1 re 3 is an enlarged taken snhstantially and Figure 1 is an enlarged iregrnentary view of the device with the cushion tread hlochs remove l.

Referring more in detail to the drawings, the invention embodies apair of spaced parallel rings or flanges 5 midvvav hetween which is disposed an annular partition 6, the

sectional view on line 33 of Figure 1,

partition 6 lacing rigidly connected to the Sldt rings 5 at suitable intervals by means ot transverse partitions 7. As shown in Figuresfi and e, the side rings 5 project in- Wardl-y beyond the inner edges of the par= titions 6 and 7 so as to engage the sides ot the tire 8, as shown particularly in Figure 3 whereby the device is held upon said tire, and the partitions 6 and 7 extend outwardly beyond the outer edges of the s ide rings 5 so that the outer edges of the latter will not contact with the ground. 4

Suitable cushion tread strips 9 are attached in any well lniow-n or preferred manner to the outer edges of the transverse partitions 7, and the opposed faces of the mom'- hers 5 and 6 are provided with axially alined ribs 10. fiushion tread hloclrs ll are fitted Within the cells produced by the partitions and are provided with grooves in the sides thereof into which the ribs 10 project when the tread blocks are forced into position, whereby said blocks are eitectively retained in place. However, any additional Welllrnovvn means may be employed for further insurin retention of the blocks ill in place.

The locks 11 may be formed of rubber or other resilient composition, and as shown in Figure 3, their outer side portions are beveled as at 12 so as to provide an interrupted tread. The hloclrs it are of such size as to have their outer edges terminate in the same circumferential relation in which the outer faces of the tread strips 9 are positioned, and it will thus he seen that effective means is provided for preventing both forward or backward and sidevvise skidding.

lin order that the device he applied to or removed from the tile 8, the hotly oi the device comprising the side rings 5 partition 6 is termed into a pluraiity oi arcuate sections, adjacent ends of which detachably and pivotally conn cted as at 1 hy means of removable pivot pins or bolts.

tlf course, the blocks 13; at these wiii be divided as at 1% to permit the sections to he swung relative to. each other. is thus apparent that when one the pins 13 is removed the device may he expanded to a greater diameter than the external diameter of the tire for permitting the removal of the device laterally oft oi the tire, While the several sections may he entireiy from each other and wronged small amount off space tie ice not required for neea Linatea attaching means includes a In order to avoid injury to the tire8 the inner edge portions of the rings 5 are outwardly curved as at 15.

In order to assist in maintaining the sections against displacement and to retain the device in position, an attaching means may This plurality of chains 16 connecting the severa sections of the device and preferabl covered as at 17 to prevent marl-ing of t e wheel, the ends of these chains bein detachably hooked into inwardly projecting ears provided on the several sections of the rings 5.

As indicated by dotted lines at 19 these chains will extend substantially straight at the inner side of the wheel to clear the brake drum of the back wheel of the vehicle, while the chains at the outer sides of the wheels will be centrally connected to radial chains 20 whose inner ends are attached to connected chains 21 that closely surround the hub 22 of the wheel. In order to insure placing of the chains under tension a spring 23 may be employed as a connection in th series of outer chains 16.

From the foregoing description it is believed that the construction and operation, as well as the advantages of the present invention will be readily understood and appreciated by those skilled in the art.

Minor changes may be made without departing from'the spirit and scope of the invention, as claimed.

What I claim as new is:

1. An anti-slipping device of the .class described comprising a pair of spaced arallel'rings, an annular'partition dispose midway between said rings, a circular series of uniformly spaced transverse partitions rigidly connecting the rings and the partition at intervals, the rings projecting inbe provided as shown in Figure l.

wardly beyond the inner edges of said partitions,-the partitions projectin outwardly beyond the outer edges of sai rings, ribs upon 0 posed faces of the annular partilel rings, an annular partition dispose mid-1 way between said rings, a circular series of uniformly spaced transverse partitions rigidly connecting the rings and the partition at intervals, the'rings projecting inwardly beyond the inner edges of said partitions, the partitions projecting outwardly beyond the outer edges of said rings, ribs upon opposed faces of the annular par tition and the rin s, cushion tread blocks disposed within t e spaces provided tween the rings and the partitions and hav ing side grooves in which said ribs are seated, said rings and the annular partition being constructed in arcuate sections deg tachably and pivotally joined in end to end relation, and cushion tread strips upon the outer edges ofthe transverse artitions, said cushion tread blocks being veled at. the

outer portions of their sides and having their outer edges terminatin in the same circumferential relation in w ich the outer surfaces of said tread strips lie, whereby an interrupted cushion tread surface is provided.

'inony whereof I aifix my signature.
